Abstract

1 / 1 resumo “mã‰todo para regular resfriamento de ã“leo, dispositivo para resfriamento de ã“leo, e, turbomãquina” a invenã§ã£o se refere a um mã©todo para regular resfriamento de ã³leo dentro de um dispositivo para resfriamento de ã³leo (10) de uma turbomã¡quina (100) compreendendo um primeiro trocador de calor (12) montado em sã©rie com um segundo trocador de calor (14), o primeiro trocador de calor (12) sendo um trocador de calor ã³leo/ar, enquanto o segundo trocador de calor (14) ã© um trocador de calor ã³leo/combustã­vel, cada trocador de calor tendo uma entrada de ã³leo (12a, 14) e uma saã­da de ã³leo (12b, 14b), um desvio (16) conectado diretamente ã  entrada de ã³leo (12) do primeiro trocador de calor (12) e ã  saã­da de ã³leo (12b) do primeiro trocador de calor (12), e um regulador de vazã£o (18) para regular a vazã£o de ã³leo que flui atravã©s do desvio (16). a circulaã§ã£o de ã³leo atravã©s do desvio (16) ã© permitida por meio do regulador de vazã£o (18) quando a temperatura de ã³leo ã© menor do que ou igual a uma temperatura predeterminada compreendida entre 70â°c e 90â°c, preferivelmente igual a aproximadamente 80â°c.1 / 1 abstract “method for regulating oil cooling, device for cooling oil, and, turbomachine†the invention refers to a method for regulating cooling of oil within a device for cooling oil (10) of a turbomachine (100) comprising a first heat exchanger (12) mounted in series with a second heat exchanger (14), the first heat exchanger ( 12) being an oil/air heat exchanger, while the second heat exchanger (14) is an oil/fuel heat exchanger, each heat exchanger having an oil inlet (12a, 14) and an oil outlet ( 12b, 14b), a bypass (16) connected directly to the oil inlet (12) of the first heat exchanger (12) and to the oil outlet (12b) of the first heat exchanger (12), and a flow regulator. o (18) to regulate the flow of oil that flows through the bypass (16). the circulation of oil through the bypass (16) is allowed by means of the flow regulator (18) when the oil temperature is less than or equal to a predetermined temperature comprised between 70° c and 90°c, preferably equal to approximately 80°c.
